However, little data exists on which probe is best for performing a supra-diaphragmatic cannulation of the subclavian vein” Lahham et al (2016).
Background: Point-of-care ultrasound guidance using a linear probe is well established as a tool to increase safety when performing a supra-diaphragmatic cannulation of the internal jugular central vein. However, little data exists on which probe is best for performing a supra-diaphragmatic cannulation of the subclavian vein.
Methods: This was a prospective, observational study at a single site emergency department where five different physician sonologists evaluate individual practice preference for visualization of the subclavian vein using a supra-clavicular approach with two different linear probes and one endocavitary probe.
Results: Of 155 patients enrolled, there was no clear preference any of the probes (p = 0.03). After pooling linear probe preference, there was a preference for either linear probe over the alternative endocavitary probe (76.8% vs. 23.1%, p < 0.05).
Conclusion: We observed a preference for a linear probe over an endocavitary probe. Further investigation is necessary to determine which probe is optimal for this application.
